On the basis of introducing the working principle and characters of newly made Gas Holdup Tool, the usage of GHT in detecting the gas well production performance is analyzed. Methods are provided for analyzing fluid property, flow status and judging water carriage in gas wells by integrating the logging data obtained from traditional densimeter and the new GHT. Based on the characters of different depth in water carried gas wells, a model is established for interpreting the water-carried gas wells.

At 2years after OPBPV,right ventricular end-diastolic volume and end-systolic volume were still significantly bigger than control group (P ＜0.01) in all patients but right ventricular ejection fraction was normal,RVEDV dilatant rate correlated very well with DB/Dp ratio significantly.

RVEDV较未手术组的扩大率与球/瓣比间有非常显著相关(P＜0.01)，RVESD扩大率与球/瓣比间有相关趋势，但球/瓣比与术后即时、3月、＞2年的ΔP↓率间无显著相关(P＞0.05)。

The rates of the heteroploidy and aneuploidy rose gradually in the shift of benign- borderline-malignancy, and the same was true for the rat es of mortality/relapse as well as the contrast risk. The nature of ovarian tumors with heteroploidy was much malignant than that with diploidy.

在良性、交界性至恶性肿瘤系列中，异倍体率或非整倍体率明显增加，病死和复发率及相对危险性随之增高；异倍体肿瘤的性质较恶，2倍体肿瘤趋于良性。

结果：革兰阴性杆菌比例显著升高，条件致病菌和酵母样真菌检出机会显著增多；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和枸橼酸杆菌等革兰阴性杆菌对喹诺酮类药物的耐药率达57%~97%，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、头孢唑啉和氨苄西林的耐药率分别为40.9%、42.4%、63.6%、70.2%、85.9%、100.0%和100.0%；链球菌和肠球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物均呈高度耐药，耐药率在36%~100%。

Secondly, we choose the proportion of shares held by institutions as dependent variable, and we use log of the total asset, volatility, beta, Jensen Index, debt-to-asset ratio, dividend yield, turnover ratio, years listed in exchange and HS300 Index dummy as explanatory variables. Then we set up a multiple regression model. Finally, we use the cross-sectional data from the end of 2006 to the end of 2007Q3 to test the relationship between the explanatory variables and the proportion held by institutions.

染液pH值、染色温度、元明粉等对上染率的影响，以及这两类染料在牛奶丝上的染色速度和提升性能的研究表明，牛奶丝染色受pH值影响很大，说明染料与酪素蛋白之间的离子键结合对染料上染起重要作用；元明粉在各pH值下对上染率的影响显示，牛奶丝的等电点约为4；酸性染料对牛奶丝的初染率高、初染速度快，但80℃恒温下的上染速度却慢于蚕丝和羊绒；牛奶丝染色对pH值的敏感性大于蚕丝和羊绒，且其酸性染料上的提升力较蚕丝和羊绒差。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
